DAMN YOU ANTI-SOVIET "FREE" WESTERNERS!!! Always downing superior Soviet technology because of it's greatness. lol (Specially you Pope, I've got my Soviet KGB agents watching you...

)
Anyway, personally, the La-7 is a great plane to fly but it's bigger than a Yak-1M (The Yak-3) so I stick mostly with the La-5FN, Yak-1M, Yak-1B, and of course the nimble little I-16/I-153. I like the Yak-1M the best because it's smaller than the rest of the planes (excluding the I-16 and I-153,) and has twin 12.7 Berezin UBS MGs and a good 20mm ShVAK cannon to boot. Plus, I find it's more nimbler than the La-7 and harder to get hit.
I don't fly the La-7 all that much, but it's a good plane... just wish there were more missions involving the Yak-1M.
